If you are using a lot of images on your blog, I’d highly suggest you use alt attributes to your images properly. It will help you increase user experience and drive traffic from search engines. But don’t do keyword stuffing in the hope of better ranking.

Do let us know if you are using any other ways to add alt tags to images. If you find this post helpful, please help me by sharing this post on Facebook, Twitter or Google+.

The problem is that the new alt tags are not automatically used in existing blogposts. You have to edit the old blog posts, insert the image with the new alt tags again, before it takes effect. Or is there a plugin to do that too?
For new blogposts / pages it works.

Thank you Istiak.You have shown me how to add alt attributes to the images I post in word press in an easy way.I will try the SEO Friendly images plug in as you suggested.
Keep up the good work Sir
Regards

Hello,
Thank you for sharing this plugin.
I developed a plugin for my own use, but I just publish it on wordpress.
My plugin “Bulk SEO Image” is useful to update all ALT attributes of your images in one clic (for example, with the post title)
Compared to other plugin, the plugin changes the ALT attribut in one time, and is not called when a page is loading
